Multimodality Cardiac Imaging, Cardiac Symptoms, and Clinical Outcomes in Patients Who Recovered from Mild COVID-19.

Background Many patients have persistent cardiac symptoms after mild COVID-19. However, studies assessing the relationship between symptoms and cardiac imaging are limited. Purpose To assess the relationship between multi-modality cardiac imaging parameters, symptoms, and clinical outcomes in patients recovered from mild COVID-19 compared to COVID-19 negative controls. Materials and Methods Patients who underwent PCR testing for SARS-CoV-2 between August 2020 and January 2022 were invited to participate in this prospective, single-center study. Participants underwent cardiac MRI, echocardiography, and assessment of cardiac symptoms at 3-6 months after SARS-CoV-2 testing. Cardiac symptoms and outcomes were also evaluated at 12-18 months. Statistical analysis included Fisher's exact test and logistic regression. Results This study included 122 participants who recovered from COVID-19 ([COVID+] mean age, 42 years ± 13 [SD]; 73 females) and 22 COVID-19 negative controls (mean age, 46 years ± 16 [SD]; 13 females). At 3-6 months, 20% (24/122) and 44% (54/122) of COVID+ participants had at least one abnormality on echocardiography and cardiac MRI, respectively, which did not differ compared to controls (23% [5/22]; P = .77 and 41% [9/22]; P = .82, respectively). However, COVID+ participants more frequently reported cardiac symptoms at 3-6 months compared to controls (48% [58/122] vs. 23% [4/22]; P = .04). An increase in native T1 (10 ms) was associated with increased odds of cardiac symptoms at 3-6 months (OR, 1.09 [95% CI: 1.00, 1.19]; P = .046) and 12-18 months (OR, 1.14 [95% CI: 1.01, 1.28]; P = .028). No major adverse cardiac events occurred during follow-up. Conclusion Patients recovered from mild COVID-19 reported increased cardiac symptoms 3-6 months after diagnosis compared to controls, but the prevalence of abnormalities on echocardiography and cardiac MRI did not differ between groups. Elevated native T1 was associated with cardiac symptoms 3-6 months and 12-18 months after mild COVID-19.

Impact of Defaulting to Single-Lumen Peripherally Inserted Central Catheters on Patient Outcomes: An Interrupted Time Series Study.

Defaulting to single-lumen peripherally inserted central catheters (PICCs) ordered from non-critical care units resulted in a sustained reduction in PICC-related complications. This system of care is transferrable to other institutions, with potential for improved patient safety and efficiency in outpatient parenteral antimicrobial therapy clinics.

Incorporating living from the heart into medical education.

Medical training poses many challenges to trainees' wellbeing. To address the impact of learning in a high turnover, high volume, acute care setting in the General Internal Medicine Clinical Teaching Unit, the Chief Medical Resident, in this personal account, shares how she and the Spiritual Care Practitioner united to form an innovative partnership. The introduction of the skills of spiritual care practitioners, generally referred to patients and families, to support medical students and residents resulted in the co-development and co-implementation of a unique, reflective, one-hour session. The objective was to create a protected space and time to discuss the impact of training and clinical experiences on medical trainees' wellbeing, in the context of "living from the heart".

Invasive Pneumococcal Disease Among Immunocompromised Persons: Implications for Vaccination Programs.

BACKGROUND: In 2012/2013, a single dose of 13-valent pneumococcal conjugate vaccine (PCV13) was recommended for immunocompromised adults in the United States and Canada. To assess the potential benefits of this recommendation, we assessed the serotype-specific burden of invasive pneumococcal disease (IPD) among immunocompromised individuals. METHODS: From 1995 to 2012, population-based surveillance for IPD was conducted in Metropolitan Toronto and Peel Region, Canada. Disease incidence and case fatality were measured in immunocompromised populations over time, and the contribution of different serotypes determined. RESULTS: Overall, 2115/7604 (28%) episodes of IPD occurred in immunocompromised persons. IPD incidence was 12-fold higher (95% confidence interval [CI], 8.7-15) in immunocompromised compared to immunocompetent persons; the case fatality rate was elevated in both younger (odds ratio [OR] 1.8) and older (OR 1.3) adults. Use of immunosuppressive medications was associated with a 2.1-2.7 fold increase in the risk of IPD. Five years after PPV23 program implementation, IPD incidence had declined significantly in immunocompromised adults (IRR 0.57, 95% CI, .40-.82). Ten years after pediatric PCV7 authorization, IPD due to PCV7 serotypes had decreased by 90% (95% CI, 77%-96%) in immunocompromised persons of all ages. In 2011/2012, 37% of isolates causing IPD in immunocompromised persons were PCV13 serotypes and 27% were PPV23/not PCV13 serotypes. CONCLUSIONS: Immunocompromised individuals comprised 28% of IPD. Both PPV23 and herd immunity from pediatric PCV7 were associated with reductions in IPD in immunocompromised populations. PCV13 vaccination of immunocompromised adults may substantially reduce the residual burden until herd immunity from pediatric PCV13 is fully established.

Impact of Reported Beta-Lactam Allergy on Inpatient Outcomes: A Multicenter Prospective Cohort Study.

BACKGROUND: Reported allergy to beta-lactam antibiotics is common and often leads to unnecessary avoidance in patients who could tolerate these antibiotics. We prospectively evaluated the impact of these reported allergies on clinical outcomes. METHODS: We conducted a trainee-led prospective cohort study to determine the burden and clinical impact of reported beta-lactam allergy on patients seen by infectious diseases consultation services at 3 academic hospitals. The primary outcome was a composite measure of readmission for the same infection, acute kidney injury, Clostridium difficile infection, or drug-related adverse reactions requiring discontinuation. Predictors of interest were history of beta-lactam allergy and receipt of preferred beta-lactam therapy. RESULTS: Among 507 patients, 95 (19%) reported beta-lactam allergy; preferred therapy was a beta-lactam in 72 (76%). When beta-lactam therapy was preferred, 25 (35%) did not receive preferred therapy due to their report of allergy even though 13 (52%) reported non-severe prior reactions. After adjustment for confounders, patients who did not receive preferred beta-lactam therapy were at greater risk of adverse events (adjusted odds ratio [aOR], 3.1; 95% confidence interval [CI], 1.28-7.89) compared with those without reported allergy. In contrast, patients who received preferred beta-lactam therapy had a similar risk of adverse events compared with patients not reporting allergy (aOR, 1.33; 95% CI, .62-2.87). CONCLUSIONS: Avoidance of preferred beta-lactam therapy in patients who report allergy is associated with an increased risk of adverse events. Development of inpatient programs aimed at accurately identifying beta-lactam allergies to safely promote beta-lactam administration among these patients is warranted.

Factors Associated With Complications of Clostridium difficile Infection in a Multicenter Prospective Cohort.

BACKGROUND: Clostridium difficile infection (CDI) is the most common cause of nosocomial infectious diarrhea and may result in severe complications including death. We conducted a prospective study to identify risk factors for complications of CDI (cCDI). METHODS: Adult inpatients with confirmed CDI in 10 Canadian hospitals were enrolled and followed for 90 days. Potential risk factors were measured within 24 hours of diagnosis. Isolates were typed by polymerase chain reaction ribotyping. cCDI was defined as 1 or more of the following: colonic perforation, toxic megacolon, colectomy, admission to an intensive care unit for cCDI, or if CDI contributed to death within 30 days of enrollment. Risk factors for cCDI were investigated by logistic regression. RESULTS: A total of 1380 patients were enrolled. cCDI was observed in 8% of patients. The ribotype was identified in 922 patients, of whom 52% were infected with R027. Age ≥ 80 years, heart rate >90/minute, respiratory rate >20/minute, white cell count <4 × 10(9)/L or ≥ 20 × 10(9)/L, albumin <25 g/L, blood urea nitrogen >7 mmol/L, and C-reactive protein ≥ 150 mg/L were independently associated with cCDI. A higher frequency of cCDI was observed among R027-infected patients (10.9% vs 7.2%), but the association was not significant in adjusted analysis. CONCLUSIONS: CDI complications were associated with older age, abnormal blood tests, and abnormal vital signs. These factors, which are readily available to clinicians at the time of diagnosis, could be used for outcome prediction and risk stratification to select patients who may need closer monitoring or more aggressive therapy.
